Are you brave enough to spend a night in the rainforest? This tour takes you deep into Khao Sok National Park, one of the world’s oldest, to experience Thailand off the beaten track. You’ll ride an elephant through the mangroves, before swapping your new friend for a wooden canoe. Your river tour will steer you past some of the park’s most ancient trees, and you’ll spot plenty of birdlife among the grassy banks. There’ll be a hike to a waterfall, too. When you reach the cascading falls, you’ll be introduced to the earth’s largest flower – the rafflesia. These blooms can grow to 75cm wide. The trip spans two full days, and you’ll bed down in a rustic tent, falling asleep to the sound of the rainforest wildlife.
